Each of the bell-shaped F-1 engines weighed over nine tons, generated 1.5 million pounds of thrust, and had a potential energy output equal to the power of eighty-five Hoover dams.

Each engine stood 18.5 feet tall and weighed 18,500 lb, as much as a loaded school bus. The reduction in parts costs is aided by using selective laser melting in the production of some metallic parts. LOX pump failures resulted in explosive fires that converted failed components into ions. They eventually hit upon a combination injector configuration and baffle arrangement that did not exhibit spontaneous instability, but the question remained, "How can you be sure it won't happen again?" A turbopump was used to inject fuel and oxygen into the combustion chamber.



In this one second, the rotor of the dual-function MK-10 centrifugal turbopump, the size of a commercial refrigerator, weighing 2,500 lb, and powered by an impulse gas turbine generating 55,000 horsepower, has spun 91.5 times.

The Saturn V could have never achieved its objective of sending humans to Earths moon were it not for the F-1 engine. He also insisted this should be accomplished by scaling up existing ballistic missile technology to produce a conservative design reliable enough for human flight.

In this one second, flight control computers referencing 15 gyroscopes have sent signals to the two, 300-pound hydraulic actuators; one for the x-axis, one for-y axis, that move this gimbal-mounted F-1 engine two degrees outboard of center.

I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. These 65 flight engines were all 100% successful.

Coming up with ways to mitigate this issue is a critical design challenge.



Pyrios uses two increased-thrust and heavily modified F-1B engines per booster.

There were small performance variations between engines on a given mission, and variations in average thrust between missions.

With 600 horsepower turbines that drive the pump at 36,000 revolutions per minute, the turbopump puts out 600 gallons of -255 degree Fahrenheit liquid methane per minute.

Thats enough to push 10 giant aircraft carriers around the ocean at nearly 25 mph.

Hence, it is critical to identify the mechanisms governing cavitation instabilities to pave the way for building principle-based design guidelines for inducers to suppress cavitation instabilities in turbopump.

A car engine generates about half a single horsepower to each pound of engine weight.
